Example Embodiment

[0030] Example 1:

[0031] Such as figure 1 Shown is the side plate of the dump truck car according to the embodiment of the present invention. The method for welding the side plate of the dump truck includes the following steps:

[0032] A. Lift the tailor-welded side plate bottom plate 14 on the platform of the first station, and place the rear large column 16, the side plate frame 11, the side plate lower frame 12, the front large column 10, and the multi-piece center column 13 and A plurality of middle transverse ribs 15 are respectively fixed on the side plate bottom plate 14 by spot welding to form the side plate of the car body. The spot welding points are on the same side of the side plate bottom plate 14. The front large pillar 10 and the rear large pillar 16 are respectively fixed to the side plate bottom plate 14 At the short sides of the two ends, the side panel frame 11 and the side panel lower frame 12 are respectively fixed on the two long sides of the side panel bot...

Example Embodiment

[0039] Example 2:

[0040] In this embodiment, the welds formed by welding the side panels of the carriage are: the center pillar 13, the middle transverse rib 15, the side panel lower frame 12, and the side panel frame 11 and the side panel bottom plate 14 are intermittent. Fillet welds, intermittent fillet welds have a fillet size of 6 mm, a weld length of 150 mm, and a distance between adjacent welds of 100 mm; the gap between the front pillar 10 and the rear pillar 16 and the side plate 14 The weld is a continuous fillet weld, and the fillet size of the continuous fillet weld is 6 mm; other features are the same as in the first embodiment.

Abstract

The invention discloses a welding method for a carriage side plate of a self-dumper, which relates to the technical field of welding. The method comprises the following steps of: welding a carriage side plate; welding a weld bead on the inner plate surface of the welded carriage side plate; performing slag removal and milling on the carriage side plate for which the weld bead on the inner plate surface is welded; overturning the carriage side plate for which the weld bead on the inner plate surface is welded, and transferring onto a platform on a fourth working station; applying pressures to the two ends of the carriage side plate by using a bending device and welding a weld bead on an outer plate surface; performing slag removal and milling on the carriage side plate for which the weld bead on the outer plate surface is welded to finish welding of the carriage side plate. Compared with the prior art, the method has the advantage that the problem of large welding bending deflection of the carriage side plate can be solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a process method for welding side panels of dump trucks. Background technique [0002] The side plate of the car is one of the important parts of the dump truck. There is a side plate of the car. A panel structure formed by welding parts such as columns in the panel and transverse ribs in the panel. The process of welding the side plate of this car is to tailor the parts that make up the side plate of the car on the platforms of several welding stations for tailor welding and welding, and each welding station is connected with a platform for transporting parts, including There is a platform, and the frame of the platform is hinged with a plurality of lifting frames through a hinge shaft, and each of the lifting frames is equipped with a roller at one end on the table surface of the platform, and the other end of each of the lifting frames is hinged with a drive A lifting oil c...
